Abstract
A process is disclosed for the separation of macromolecules from a fluid substance containing the macromolecules. The process comprises contacting the fluid substance with discrete porous particles having an interconnected porosity throughout which provides an extended surface area and a pore structure such as will allow the macromolecules to permeate the particles and be sorbed, the discrete porous particles being selected such that a proportion thereof have acidic surfaces for contacting the macromolecules in the fluid substance and a proportion thereof have basic surfaces for contacting the macromolecules in the fluid substance. A process for the separation of protein from milk whey solution is also disclosed.

A process for the separation of macromolecules from a fluid substance containing the macromolecules which comprises contacting the fluid substance with discrete porous absorbent particles of inorganic material having an interconnected porosity throughout which provides an extended surface area and a pore structure such as will allow the macromolecules to permeate the particles and be sorbed, the pores of said particles having a diameter in the range of 1,000 to 10,000 A, the discrete porous particles being selected such that a proportion thereof have acidic surfaces for contacting the macromolecules in the fluid substance and a proportion thereof have basic surfaces for contacting the macromolecules in the fluid substance.
A process for the separation of protein from a milk whey solution comprising contacting the solution with discrete porous absorbent particles of inorganic material having an interconnected porosity throughout which provides an extended surfaces area and a pore structure such as will allow protein to permeate the particles and be sorbed, a proportion of the particles having acidic surfaces for contacting protein and a proportion having basic surfaces for contacting protein.
